The little lad has been left devastated by the breakdown of his dad Peter’s marriage to Leanne – and the troubled youngster blames knicker factory owner Carla for all his problems.

So when Leanne returns from her sister Toyah’s house to collect the rest of her belongings, the boy pulls out all the stops to persuade her to stay.

He tells Leanne that Carla has been getting drunk and hitting him – sparking the feisty babe into violent action.

Without giving it a second thought, the protective mum storms into the factory to confront Carla.

And, as our dramatic pictures show, the two women have a vicious fight in the middle of the factory – much to evil Frank Foster’s amusement.

Michelle Connor manages to separate the warring pair but, before she leaves, Leanne warns Carla to stay away from Simon.

A Coronation Street insider said: “Leanne has no intention of staying on in Weatherfield but when Simon tells her she can’t leave again because Carla has been hitting him, she knows she has to stay for him. None of it is his fault and his whole world is collapsing.

“Peter’s dad Ken fills her in on everything that’s been going on with him at school so she doesn’t even consider that he’s lying.

“She goes for Carla the moment she walks into the factory.

“She’s spent the last few weeks away thinking about all the things she’s wanted to do to Carla and Simon gives her the perfect opportunity to do it.

“She’s absolutely full of rage when she attacks Carla. This is one soap showdown fans will not want to miss.”

Fans of the hit ITV1 soap will be able to watch the catfight between Leanne and Carla a week tomorrow.
